BORING-ROD FOR WELL-AUGERS.

SPECIFICATION forming part of Letters Patent N. 557,482, *dated March 31, 1896. Application led April 20, 1895. Serial No. 546,495. (No model.)

To all whom, it may concern,.-

Beit known that we, HENRY C. BRUNER and LESLIE BRUNER, citizens of the United States, residing in the township of Exira, in the county of Audubon and State of Iowa, have invented certain new and useful Improvements in Boring-Rods for fell-Angers; and we do declare the following to be a full, clear, and exact description of the invention, such as will lenable others skilled in the art to which it appertains to make and use the-same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in boring-rods for well-angers; and it consists in the peculiar construction and combination of the parts that will be more fully set forth hereinafter, and particularly pointed out in the claims.

The objects of our invention are to facilitate the boring of wells and to provide a sectional boring-rod by means of which the auger, when constructing a well, can be raised and emptied without disconnecting any of the sections of the boring-rod. We attain these objects by the device illustrated in the accompanying drawings, in which- Figure l is a view in side elevation of the boring-rod connected to a portion of a boring-machine. Fig. 2 is a similar enlarged detailed view of a section of the boring-rod, having a part of its upper end cut away so as to show the coupling-clutch within. Fig. 3 is a similar enlarged detailed view of the plug that connects the boring-rod and the auger. Fig. 4 is a detailed perspective view of the clamp and swivel connected thereto, and Fig. 5 is an enlarged detailed view in side elevation of the swivel.

Similar letters refer to similar parts throughout the several views.

In the accompanying drawings, B represents the boring-rod, composed of the sections a, b, c, and d. Section a is made square and solid, section b round and solid, section c round and hollow, and section cl round and hollow. All of the sections of the boringrod can be constructed square; but we prefer to construct all the sections, excepting the one at the top, round, for the reason that in use the sections are liable to become twisted, and when a square section becomes twisted it cannot be slid into the section below it with which it is connected. The sections are each constructed about twenty feet in length, and the boring-rod can be constructed of a suiiicient number of sections to reach any desired depth. All of the sections, excepting the two at the top7 are made hollow, and each section, excepting the top one, is constructed of suitable size to readily slide into the one next below it. Each of the hollow sections has formed at its upper end on its inner surface a coupling-clutch similar to clutch i, (shown in Fig. 2,) and each has formed at its lower end on its outer surface a coupling-clutch similar to clutch t, as shown on the lower end of section d. The section b is also provided at its lower end with a similar coupling-clutch. The sections ct and b are secured together by means of the coupling-clutches fm and n and the pin f,which passes through the couplingm and the section ZJ. The coupling-clutch on the lower end of section b engages with the coupling-clutch on the inner surface of the upper end of section c, and the couplingclutch on the lower end of section c engages with the coupling-clutch on the inner surface of the upper end of section d, and if other sections are added to the rod they are so constructed that the coupling-clutch on the outer surface of the lower end of each engages with the coupling-clutch on the inner surface of the upper end of the section next below. The upwardly and downwardly extending, edges of the coupling-clutches are inclined from the perpendicular, so that the boring-rod will not collapse when in use.

D is a plug that connects the rod to the auger. It is provided with a series of apertures o, adapted to receive the pin f', and with the tenon y and the coupling-clutches r, s, a", and 6. J is a portion of an ordinary wellauger, which is provided at its upper end with the socket a', adapted to receive the tenon y. The plug D is secured to the well-auger by inserting the tenen g/ into the socket a and by passing the pin c through the socket and tenon. That portion of the plug D marked c is adapted to enter the clutches on the lower ends of sections ce and b, and the portion marked f to enter the lower end of section c, and the portion marked g to enter the lower end of section d, and the portion marked 7i. to enter, if added, the section next below sectiond. The clutch r of the plug D is adapted to engage with the clutches on the lower ends of sections a and b, the clutch s with the clutch on the lower end of section c, the clutch a!" with the clutch on the lower end oi' section d, and the clutch 6 with the clutch on the lower end of any added section. The plug D is secured to the rod B by means of the clutches and the pin j", which passes through the lower end of the section to which the plug is secured and through the proper aperture u of the plug. K is a clamp which is secured to the upper end of the lower section of the rod B, and which is provided with the swivel e. A is a portion of an ordinary boring-machine frame.

f" is a swivel secured to the upper end of section a.

I is a derrick pivoted to the frame A.

M and N are pulleys secured to the upper end of the derrick.

L and P are ropes.

ll is a spool mounted upon the frame A, to which one end of the rope P is secured.

G is a spoohmounted upon the frame A, to which one end of the rope L is secured.

g is a crank secured to the shaft of the spool H, and 7L' is a crank secured to the shaft of the spool G.

The rope L passes over the pulley M and the rope P over the pulley N. b is a hook secured to the lower end of the rope L, which engages with the swivel e.

n is a hook secured to the end of the rope P, and which engages with the staple m of the swivel F, and which is also adapted to enter the aperture in the swivel f of the rod B.

R is a clamp which straddles section a of the rod B, and which is secured to section a by the pin c", and which is adjustable up and down upon section a.. It supports the swivel F, which can be removed from the clamp by withdrawing the pin a" and the piece or slide d'. The swivel F is provided with the aperture g, through which the rope L loosely passes, and has firmly secured to its top the staple in.

The spools H and G can be operated by turning the cranks attached to their respective shafts, but are preferably operated by connecting machinery and power, such as is usually employed in boring-machines and well-angers.

The rod B is revolved by the means usually employed in boring-machines and well-augers. The ropes L and P are prevented from twisting together when the rod is revolved by means of securing the rope P to the swivel F and passing the rope L loosely through the aperture g" of the swivel.

NVell-au gers of boring-machines in common use cannot be drawn up and emptied from a distance greater than the length of two sections of the boring-rod without disconnecting and removing one or more sections thereof, which operation takes considerable time and hard work of the operators every time the auger is emptied and which is obviated by the use of the boring-rod herein described.

Our improved boring-rod is operated similar to those in common use until a depth is reached equal to the length of two sections of the rod; but when a greater depth is reached then hollow sections are attached to the rod from time to time, as the depth increases, by sliding them on over the top of the rod, and the rod is then operated to withdraw the auger from and replace it within the well, as follows Hold the spool H so that it cannot revolve, and revolve the spool G and wind the rope L thereon until the sliding sections of the rod close together and the weight is removed from the rope P. Then detach the rope P from the swivel F and remove the swivel from the clamp R and permit it to slide down on the rope L. Then further revolve the spool G and wind the rope L thereon until the rod, with the auger attached thereto, is lifted entirely out of the ground and a sufticient distance above the ground to permit the auger to be readily emptied of its contents. Then unwind the rope L from the spool G until all the sections of the rod, excepting the 011e at the top, are in the ground. Then replace the swivel F within the clamp R and attach to it the rope P and prevent the spool H from revolving. Then further unwind the rope L from the spool G and permit the rod to extend and carry the auger to the bottom of the well.

Having described our invention, whatwe claim as new, and desire to secure by Letters Patent, is-

l. The combination of the boring-rod composed of sections which slide onto each other, the swivel secured to the upper section of the rod, the swivel secured to the lower section of the rod, the ropes one of which is connected with the swivel that is secured to the upper section of the rod, and the other passes loosely through it and is secured at its lower end to the swivel that is secured to the lower section of the rod, and the plug for connecting the boring-rod with the auger, having a series of coupling-clutches of various diameters, adapted to engage with the couplingclutches on the boring-rod, substantially as described.

2. The combination of the boring-rod composed of sections which slide onto cach other,
